Description

The present invention relates to a system for monitoring a business using a moving image including a web camera and a still image photographing device, and more particularly to a business monitoring system using a moving image including a web camera controlled by RFID and a still image photographing device.

Recently, with the increase in capacity of storage media and storage devices, a system for monitoring work with a video camera is used for the purpose of preventing accidents and crimes in various work. However, with a conventional surveillance system that continues to shoot the work area where the work and the work are being performed on the video, let's trace the cause and the scope of the defect when a defect is found in the product related to the work accident or work. Even so, it is a time-consuming task to search for images related to acupuncture from an enormous amount of video data, and it is a problematic system to realize high-level traceability that requires prompt response.

Furthermore, the conventional method of photographing a work area cannot be intentionally photographed for the object to be traced, and it is necessary to search for an image focused on the object over a long period of time, which is inefficient. It was the target.

As a system aiming at clear recording in response to a predetermined trigger, rather than simply recording an image, there is a system described in Patent Document 1. Here, a plurality of cameras having pan, tilde, and zoom functions are installed at a shooting target location, a motion detection trigger by successive comparison of captured images, a trigger by an operation of a web browser of a personal computer at a monitoring center, and a fixed cycle Various triggers, such as a trigger automatically generated at a predetermined interval and a trigger by operating an emergency button, are set and recorded in the monitoring information. Even if there is no difference, it is possible to clearly shoot a subject that contains a major medical error or accident, or to take a picture according to the timing of work, and record the image while associating the photographed image with a prescription instruction. It is not enough to achieve high traceability.
